FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 240,909, dated May 3, 1881.

` Application filed November 23, 188D. (No model.)

T o all whom it may concern:

Be it known that I, ALBERT J. KLETZKER,

a citizen of the United States, residing at Stg a flexible slitted barrel-pen or writing-p.oint

connected to and operating a needle clearer or valve, by which the flow of ink to the pen is regulated and controlled.

Secondly, in the provision, on a slotted writing-point for fountain-pens, of a projecting toe for operating the clearer needle or valve, as

will hereinafter more fully appear.v

Thirdly, in the provision, in a fountain-pen, of a clearer needle or stem provided with duplicate valves which rest in corresponding seats in the casing of the pen to shut oft' the ow of the ink when the pen is not in use. It is preferred to make these valves self-closing, and this is accomplished by means of a spiral spring which is preferably arranged within the air-tube out of contact with the ink, so as not to be corroded or affected in any manner by the same, all as will hereinafter more fully appear.

Fourthly, in the provision, ina fountain-pen, ot' a needle clearer or valve having a valve which controls both the ink and ait` openings, so as to place the flow of ink entirely under control and prevent any leakage wh en thepen is not in use. 4 v

Fifthly, in certain details of construction, as will hereinafter more full appear.

In the drawings, Figure l-is an enlarged vertical section. Fig. 2 is a detail section of the writin g portion. l Fig. 3 is a perspective view of the writing-barrel point.

The hollow fountain or ink-handle A is of any usual shape and construction, having its topl formed with a valve-seat for the valve b of the screw-cap B.

C is a slitted writing-point, which is of acylindrical shape at its upper end, where itis atquent movement of the clearer in the boreot' i said point is continuous during the use ot' the pen, so that said bore or passage will be kept clear and a constant supply of ink carried to the writing-point. The toe c is preferably formed on the writing-point in the manner shown in Fig. 3, so that the spring or" the Writing-point will be above said toe, so as to impart the necessary movement to the same.

The point-holder D is removably attached to the tapering-point section E, so as to be easily detached for cleaning purposes, dto.

In use any suitable material, either vulcanite, celluloid, metal, &c., may be used in the construction of the handle A, cap B, taperingpoint section E, and point-holder D, and the slitted writing-point G will be of any suitable metal, such as gold, steel, 85o.

' The clearer or stem c is formed witli plugvalves c2 c3, which are seated in suitable valveseats on the cylindrical portion ofthe point C and the bottom of the handle A, as shown, and the valve c3, in addition to controlling the inksupply, also controls the air-supply openings a ot' the air or vent tube A', so as to render the flow of ink more regular and automatic. The needle clearer or stem c', with its valves c2 c3, are drawn upward by a spring, a', arranged within the air-tube A', as shown. The stem-extension c4, on which the spring acts, passes up through the air-supply opening a, as clearly shown in Fig. l.

The air-tube A' is attached to the side of the ink-receptacle A, so as to form a stronger and more rigid connection, and it is provided with a vent-hole, a2,'near its upper end, as shown.

The toe c may be formed on or attached to the writing-point in any suitable manner without departing from the spirit of my invention.

v I am aware that prior to my invention fountain-pens have been constructed with slitted Writing-points in connection with clearer-needles; but in such cases the needle --clearers rested directly on the paper, and were not atlod tached to or operated by the Writing-poin t, as in my construction.

I am also aware that it is not new to operate an ink-controlling valve in a fountain-pen by the springing of the pen-point in use, such construction being shown in Patent No. 7 0,453, issued November 5, 1867, to G. R. Metten, for an improvement in fountain-pens. I therefore do not claim such combination broadly; but

What I do claim as my invention is- 1. In afountain-pen, a barrel or slitted writing-point connected to and operating a needle-clearer by the springing of the pen-point in use, said clearer having valve or valves for controllingthe How of ink, substantially as and for the purpose set forth.

2. The combination,with a fountain-pen having a vertically-moving needle or clearer, c.of

a slitted pen or writing-poing@provided with 4. The combination, in a fountain-pen having a barrel or slitted writing-point, C, of the needle-clearer c', drawn upward by a spring, a', and havin gvalves c2 c3, situated as described and opening downward, in the manner herein described, and for the purpose set forth.

5. The combination, in a fountainpen having a barrel or slitted writing-point, C, and a needle-clearer, c', provided with valves c2 c3, situated as described and opening downward, of the spring a', arranged in the air-tube A', all as herein described, and for the` purpose set forth.

6. The combination of the ink-chamber and air-tube, having their outlet-openin gs situated as described, with the needle-clearer, having a Valve, c3, controlling the ink and air supply openings,as described,and for the purpose set forth.

In testimony whereof wit-ness my hand this 18th day of November, 1880.

ALBERT J. KLET'ZKER.l

In presence of- WM. MENART, ROBERT BURNS.
